When the sash Vis in place the front nange will Figure 5 is a perspectiveview of a portiono be forced against the rjuxtaposed wall of 'the a sash with weather strippingA embodyingl .my window frame and effectively seal the 'sashin the window frame. 55=l If the opening between the bead'and the wall of the slot is too wide for the Weather stripping to closely fit therein a separator member I2 may be driven in between the front and rear flanges to cause them to flare outwardly into engagement with the juxtaposed walls of the bead and window frame.

If desired the front flange may have its front marginal portion inwardly deflected as at I3, Figure 8. Y

The front flange I may also be deflected rearwardly upon itself as at I4, Figure 9, the hinge for such flange being at I5. This reinforces the flange I0 so that the flanges I0 and I4 will be in close engagement with the juxtaposed walls of the sash and Window frame.

In some cases the rear flange may be omitted as shown in Figure 7, in which case the body flange I6 is insertable alongside of the bead and the spring flange I1 extends outwardly therefrom to form an obtuse angle.

The top of the upper sash and the bottom of the.y lower sash is sealed by a different form of weather stripping and I preferably employ the construction seen in Figures 5 and 6, wherein theY strip has a flat body portion I8 secured by fastening devices I9 to the sash, and provided witha preferably deflected hinge portion 20 which merges into the outwardly flared spring flange 2|. The edge of the sash rail is bevelled off as at 22 to receive the hinge 20, if the latter is offset.

The weather stripping canbe economically formed from spring metal in sheet form.

vIf after being in use for along time the spring flange becomes more or less set, it can be flared outwardly by drawing a screw driver, knife or other tool along its inner wall.

When the weather stripping is to be applied tofwindow frames already installed and in use and the bead 3 closely engages thewall of the slot 2, a knife or other. tool can be used along the beadto provide sufficient clearance for the insertion of .the flanges 1 and 8 of the weather stripping.

The flanges l and 8 form an angularly shaped seal for the spacebetween the side of the sash and the window frame and between the window frameand `the bead. y

InA the embodiment seen in Figure 11, the strip is folded upon itself to form a body flange 24a front vflange 25 anda laterally extending flange 26 which terminates in an inwardly offset` rounded hinge portion 21, adapted to seat lin a groove `28, in the window frame, and con- `is not offset, -it is not necessary to employ the groove 28,; as is apparent. i

If after a long period of use the spring flangesy such as I5 or 29 become more or less set, they can be bent outwardly to their originalV position by running a suitabletool `between them and the juxtaposed laterally extending flange such as IU or- 26.

The embodiments seen in Figures 9 and 11v provide a very effective seal since it may be securely wedged alongside of the dividing strip or bead, with ,the flange IU or 26 engaging `the window frame,r and with the spring flange pressing against the sash. f

In all of the embodiments of my invention as herein shown, I provide a spring flange which exerts a continuous spring pressure to form an effective seal. The hinge may be flat but it is preferably rounded to render it more durable.

The weather-stripping at its ends may be tacked to the window frame if desired lalthough this is not necessary as it has a friction fit between the bead and the sash.

It will now be apparent that I have devised a new and useful weather-stripping, which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described preferred embodiments thereofy which will give in practice satisfactory and reliable results, it is to be understood that these embodiments are susceptible of modification vin various particulars without departing from the spirit or scope of the invention or sacrificing any of its. advantages.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent isz- 1. The combination with a window frame, having a slot with a bead in the slot, and the window sash, of a weather strip of spring material comprising a rear flat flange merging into a flat front flange deflected over it, with said flanges inserted between the beadvand a side wall of thev slot, said front and rear flangesrbeing bendable tovseal the space between the bead and the juxtaposed wall of yits slot, said front flange merging into an outwardly extending flange at right angles to it and contacting with the window frame to effect a seal with a wall of the window frame, said rear flange effecting a seal with the window sash, said right angler flange merging into an inwardly extending spring flange disposed at an angle to it and bearing against the outer wall of the sash.

2. The combination with a window frame, having a groove, a slot with a bead in the slot, and the window sash,V of a weather strip of spring material comprising a vrear flat flange merging into a flat front flange deflected over it and contacting Ywith it throughout its area, with said flanges inserted between the bead and a side Wall of the slot, said rear flange extendingr to overlie the window sash, lsaid front flange merging into an outwardly extending flange at right anglesl to it and contacting withl the window frame, said right angle flange merging by an offset hinge portion into an inwardly wall of said slot, said front flange merging into` an outwardly extending flange at right angles to it and contacting with the window frame, said right angle flange merging by an offset hinge portion with an inwardly extending spring flange disposed at an'an'gle to the right'angle flange, said spring flange bearing against' the outer wall of the sash.
